Here’s a great quote on how to read the Bible and apply it in every circumstance, as Christ must always be the hermeutical key. Take from Instruments in the Redeemer’s Hands: People in Need of Change Helping People in Need of Change (Resources for Changing Lives) by Paul David Tripp.
That is how Scripture differs from an encyclopedia. When I use an encyclopedia, I do not need to read other articles to understand the one I am reading at the moment. One article has no connection to another; there are no overarching themes. In the Bible, however, every passage is dependent on the whole, and the whole Bible is held together by interdependent themes that run through every passage like rebar, the steel rods that reinforce concrete. If I handle Scripture topically, I will miss the overarching themes at the heart of everything else God wants to say to me. These themes give me a sense of identity, purpose, and direction that will fundamentally alter the way I think, desire, speak, and act. They will go to the root of my problem, producing change that lasts.
The sad fact is that many of us are simply not biblical in the way we use the Bible! Being biblical does not mean merely quoting words from within its pages. Being truly biblical means that my counsel reflects what the entire Bible is about. The Bible is a narrative, a story of redemption, and its chief character is Jesus Christ. He is the main theme of the narrative, and he is revealed in every passage in the book. This story reveals how God harnessed nature and controlled history to send his Son to rescue rebellious, foolish, and self-focused men and women. He freed them from bondage to themselves, enabled them to live for his glory, and gifted them with an eternity in his presence, far from the harsh realities of the Fall. (pp. 26-27)
